“…Chiba et al carried out ocean experiment using DEGs installed on a buoy in Tampa Bay, 1.6 km off the cost, a water depth of~5 m. The DEG was able to generate a peak power of 1.2 W and average power of 2.5 W at 10 cm wave height (Chiba et al 2008(Chiba et al , 2011. Other DEGs to utilize the energy of wave motion are being developed by SBM Offshore in Monaco (Czech et al 2010) and PolyWEC in Spain (Moretti et al 2014). …”

“…Since failure by dielectric breakdown is of no concern for this scheme this allows the DE to be operated closer to its dielectric breakdown strength (Section 4). Czech et al [14] analytically compared the ideal constant voltage, constant charge and constant electric field schemes and found that the constant electric field was the most effective. However, it should be noted that maximising the energy output by increasing the electric field may have an adverse effect on the lifespan of the generator [15].…”

Dielectric elastomers are a type of electroactive polymers that can be conveniently used as sensors, actuators or energy harvesters and the latter is the focus of this review. The relatively high number of publications devoted to dielectric elastomers in recent years is a direct reflection of their diversity, applicability as well as nontrivial electrical and mechanical properties. This chapter provides a review of fundamental mechanical and electrical properties of dielectric elastomers and up-to-date information regarding new developments of this technology and it's potential applications for energy harvesting from various vibration sources explored over the past decade.

“…11 There are several works involving on the basic working principle. [12][13][14] Fundamentals of dielectric elastomer in generator, actuator, and sensor mode are described in these works. In the actuator mode, electrical energy is converted into mechanical work by bringing opposite charged layers closer together.…”

This paper proposes a design and modeling of an innovative wave energy converter using Dielectric electro active polymer (DEAP). Firstly, an accurate model of conventional DEAP generator is investigated and validated under a specific range of ocean waves. Then, a structure design of an antagonistic DEAP generator so-called energy capture unit (ECU), which consists of two DEAPs in antagonistic connection mode to increase harvested energy efficiency, is modeled and validated by experimental data. A new design of WECs is then developed with array of ECUs to increase the output energy. In addition, by using the linear potential wave theory, the hydrodynamic forces are calculated under regular wave conditions. Consequently, a complete analytical model of the proposed WECs using multiple ECUs under hydrodynamic behavior is then obtained to investigate the performance of energy conversion. Finally, based on the developed analytical model, the stretch ratio known as an important factor to efficiency and output power is investigated under the influence of the floating buoy's mass. Then, the resonance behavior of the WECs with a typical wave frequency can be tuned by optimizing the floating's mass to increase the degree of utilization of the device. The simulation results indicate that the efficiency of wave energy converter can be up to 25% thanks to resonance behavior.
